通过消除两个以上声子的贡献,我们引入了H.Fröhlich极化子哈密顿量中至多一个声子的极化子模型。研究了这种0,1声子极化子模型的光谱性质。结果表明,在弱耦合区域,由0,1声子极化子模型得到的最低能量和有效质量与H.Fröhlich极化子哈密顿量的结果一致。
We introduce the polaron model with at most one phonon from the H. Fröhlich polaron Hamiltonian by eliminating contributions from more than two phonons. Spectral properties of this 0,1-phonon polaron model are investigated. It is clarified that, in the weak coupling region, the lowest energy and the effective mass obtained from the 0,1-phonon polaron model agree with those of the H. Fröhlich polaron Hamiltonian.
